Title: Improvements in thermomagnetic image reproduction
IPC: B41M5/26
Filed: 1965-11-09
Abstract: 1,133,707. Thermomagnetic images. E. I. DU PONT DE NEMOURS & CO. 9 Nov., 1965 [9 Nov., 1964], No. 47558/65. Heading B6C. [Also in Division G5] A thermomagnetic imaging process comprises reading information to be reproduced or recorded into a magnetic recording member with the aid of radiation selectively impinged on the member, wherein the member comprises fine, discrete particles of a material magnetizable to a hard magnetic state having an energy product (BH)max of 0À08-8À0 gauss oersteds x 10<SP>6</SP>, a remanence B# of 500-21,500 gauss, a coercivity H c  of 40-6000 oersteds and a Curie temperature not exceeding 1200‹ C. and contained in a stratum carried by a support, the intensity of the impinging radiation being such that in the areas where the radiation is impinged the temperature of the magnetic material is raised above its Curie temperature while in the areas where the radiation is not impinged it remains below the Curie temperature, while maintaining the recording member in a state such that its magnetic state will change above, but not below, the Curie temperature, and reading-out the resulting magnetic image, The information may be read-in by exposing the recording member to the radiation through an information carrier which is imagewise transparent to the radiation, or focusing a beam of actinic radiation, a laser beam or an electron beam on to the member and moving the beam in an image pattern e.g. by electronic or optical means. The electron beam may be caused to move in a series of lines (rasters). The magnetic image may be read-out by a sensing head coupled to give an oscilloscope trace or a television picture or by developing the image with a magnetic powder e.g. finely powdered metallic iron. The developed image may be transferred by contact to a receptor e.g. paper. Other methods of reading-out the image are using polarized light (Faraday and Kerr effects), electron beam sensing, using the break-up of the spectral lines of a light source in a magnetic field (Zeeman effect), and the use of a magnetic tape viewer. The magnetizable stratum may be supported in and/or on glass, a polymer, paper, cardboard or wood. The preferred exposure source is a high voltage, high intensity photographic flash lamp e.g. a xenon lamp. In a further embodiment the recording member may be imagewise exposed to radiation in the presence of a magnetic field insufficient to magnetize the film at room temperature or at some elevated biasing temperature, the additional energy supplied by the exposing radiation causing selective magnetization.

Title: Fuel supply device for internal combustion engine
IPC: F02D41/34
Filed: 1976-11-16
Abstract: 1521393 IC engine fuel supply system SOC INDUSTRIELLE DE BREVETS ET D'ETUDES 16 Nov 1976 [20 Nov 1975] 47709/76 Heading F1B [Also in Division G3] In an I.C. engine fuel supply system, a continuous energization signal is supplied to the injector valve 16 from when an engine starter motor is energized until when the associated I.C. engine has reached a predetermined speed or until a set time (which depends on temperature and may be zero if the temperature is above, for example, 50C) has elapsed, whichever is first. When the engine is running, the opening time of the injector valve 16 is dependent on air-flow detected by auxiliary throttle valve 3 whose rotation varies a potentiometer 12 connected to electronic circuit 15 whose output signal actuates valve 16. Temperature, e.g. of engine coolant, is sensed by an NTC resistor 31 and also acts on a capsule 28 to vary the flow through an extra air duct 26. A regulator 21 may maintain the fuel pressure constant at injector 16, during normal running (the length of the energizing signals to the injector then being variable in dependence on the pressure between the throttle valves) and reduce it to a lower value during continuous injection or the fuel pressure may be regulated to be proportional to the depression between the throttle valves. When the starter motor is energized a voltage is applied to a flipflop 50 which gives an output via OR gate 45 to amplifier 52 which opens injector valves 53. When the engine is running a NAND gate 47 receives a square wave signal from a univibrator 48 and a square wave having a duration related to engine speed from an inverter 46. When the resistance 31 is cold the duration of waves from the univibrator is less than that of waves from the inverter so the flip-flop 50 remains in the same state. When the engine reaches the predetermined speed, (dependent on the value of resistance 31 and therefore on temperature) the waves from inverter 46 become shorter than those from the univibrator 48 so that flip-flops 49 and 50 change condition, the subsequent operation of the injector valves 53 being intermittent and controlled by saw-tooth pulses from transistors 42, 43. Continuous injection may be stopped after a given time by a gate (not shown) between flip-flop 50 and OR gate 45 and a timing circuit which provides a gate-enabling signal for the given time from initial energization of the starter motor. The timing circuit may include a thermistor subject to engine temperature.

A pipe coupling device comprises two tubular members each adapted for connection to a pipe, each containing similar connecting members and each carrying valve means automatically opened on connection of the coupling. In one embodiment (Fig. 2) each tubular member 10 contains a spring- loaded valve member 19 slidably mounted in a spider 17 and carrying a stem 21 projecting beyond the face of the tubular member 10. The outer surface of the member 10 carries a knurled slidable sleeve 23 having a flange 24 abutting an annular rib 14 on the tubular member when the coupling is connected and having interrupted screw threads engageable with corresponding interrupted threads on the end of the abutting tubular member.

In a second embodiment (Fig. 5) each tubular member 29 contains a spring-loaded sleeve 36 and valve 35 which extend equal distances from the tubular member in the uncoupled state, the sleeve forming a seal for the coupling as the two members are brought together. The tubular members are connected together by means of a bayonet-type fastening (Fig. 7, not shown). The first embodiment may also carry similar internal sleeves (Fig. 4, not shown) to seal the pipes together before the valves are opened, modified in that the said sleeves are integral with the end of the projecting stems 21 of the valves.

Abstract: 1413920 Camera and flash WEST ELECTRIC CO Ltd 23 Oct 1973 [26 Oct 1972] 49247/73 Heading G2A A camera has a switch 2 for changing over from flash to non-flash operation, which at the same time changes a light-limiting device in front of the lens. As shown, an angled plate 3 integral with the switch 2 has different-sized apertures 4 and 5. When the ambient light is sufficient not to require flash illumination, switch 2 is pushed to the OFF position, which brings the smaller aperture 4 in front of the lens 6. With low ambient light, switch 2 is pushed to the ON position, which sets the camera so that the flash 8 is actuated in synchronism with the shutter. This brings the larger aperture 5 into the light path. These two apertures correspond to suitable f-values. Figs. (not shown) 5, 6 and 7 are of different arrangements of aperture settings which are brought into alignment with the lens by movement of switch 2. Instead of diaphragm apertures of different sizes, colour filters of different densities may be used.
